Galaxy Formation With Ultralight Bosonic Dark Matter
(2020-05-18)Ultralight bosonic particles forming a coherent state are dark matter candidates with distinctive wave-like behaviour on the scale of dwarf galaxies and below. In this thesis, a new simulation technique for ultralight ... -
GaN:Gd - Ein verdünnter magnetischer Halbleiter?
(2011-03-09)In this thesis the magnetic properties of GaN:Gd layers grown by molecular beam epitaxy (MBE) are adressed. Structural analysis confirmes the substitutional incorporation of Gd on a Ga site ... -
Gefügebildung und Verdichtungsvorgänge bei weichmagnetischen Ferriten
(2006-07-13)Microstructural tailoring is used to modify the electromagnetic properties of softmagnetic MnZn and NiZn ferrites, which are broadly used in all types of electronics.High permeability MnZn ... -
Geometric structure and mechanical stability of disordered tetrahedra packings
(2013-12-18)In this study, the geometric structure of frictional, disordered tetrahedra packings is analysed in detail via X-ray Computed Tomography. The choice of the granulate is motivated by moving away from the "spherical cow" ... -
Gestaltung der elektronischen Korrelationen in Perowskit-Heterostrukturen auf atomarer Skala
(2016-01-19)For the deposition of high quality heterostructures consisting of transition metal perovskites a new system for metalorganic aerosol deposition with growth control by in-situ ellipsometry was developed. By numerical ... -
Glättungsmechanismen beim Ionenbeschuss rauer amorpher Oberflächen
(2008-03-18)Investigation of surface structures constitutes a broad field of contemporary research. Particularly due to proceeding miniaturization of electronic devices controlling the formation and evolution of surfaces and ... -
Global magneto-convection models of stars with varying rotation rate
(2020-06-12)The solar magnetic field is mostly axisymmetric at the largest scale. Latitudinal dynamo waves propagate from mid-latitudes towards the equator, as can be seen, for example, from sunspot observations. Reproducing this ... -
Goal-Oriented Control of Self-Organizing Behavior in Autonomous Robots
(2010-05-18)We study adaptive control algorithms within a dynamical systems approach for autonomous robots that cause the self-organization of coordinated behaviors without specific goals or particular ... -

Graphen auf Siliziumcarbid: elektronische Eigenschaften und Ladungstransport
(2014-06-10)In this thesis the local electronic as well as charge transport properties down to atomic length scales of epitaxial graphene on the SiC(0001) surface are investigated. To achieve this, next to well known scanning probe ... -
Gravitational Microlensing: GPU-based Simulation Algorithms and the Information Content of Light Curves
(2011-07-22)The simulation of gravitational microlensing light curves is a time-consuming effort, but essential for confirming potential planetary microlensing events. In this thesis a point-wise binary ... -
Grenzflächeneffekte in Manganatschichten
(2008-01-07)Interfaces play a major role in manganites and magnetoresistive systems. Thus, this work deals with the systematic analysis of the influence of interfaces on the transport properties of ... -
Ground State Depletion Fluorescence Microscopy
(2008-01-16)Microscopy is one of the most important analysis tools of modern science. One defining attribute of a microscope is its resolution as it specifies the minimum distance at which one can ... -
Growth and Characterization of Carbon-Metal-Nanocomposite-Thin-Films and Self-Organized Layer Growth
(2009-06-09)The simultaneous deposition of carbon and metal ions by mass-selected ion beam deposition leads to the formation of carbon-metal-nanocomposites. The morphology of the resulting films depends ... -
Die großräumige Umgebung von QSO/Seyfertgalaxien bei nahen und kosmologischen Rotverschiebungen
(2011-12-06)The goal of this thesis is to study the properties of galaxies in the environment of a quasar as a function of the characteristics of this central quasar. In addition, the galaxies in the ... -
Grundzustandsstruktur ungeordneter Systeme und Dynamik von Optimierungsalgorithmen
(2005-12-12)Combinatorial optimization problems from Theoretical Computer Sciences and certain magnetic alloys (called spin glasses) both consist of particles or variables which are coupled by a large ... -
HappyFace as a monitoring tool for the ATLAS experiment
(2016-10-24)The importance of monitoring on HEP grid computing systems is growing due to a significant increase in their complexity. Computer scientists and administrators have been studying and building effective ways to gather ... -
